Ziihao 6Pcs Ultrasonic Sensor Module Kit HC-SR04 Distance Sensor with 3pcs Mounting Bracket Compatible with Ardu-ino UNO Mega R3 Mega2560 Duemilanove Nano Rapsberry Pi 3 Robot XBee ZigBee
Specification:Power Supply: DC 5VQuiescent Current : <2mAEffectual Angle: <15°Ranging Distance: 2 - 500cmTrigger Input Pulse Width: 10uSResolution : 0.3cmDimensions: 1.3 x 0.4 x 0.1in / 3.03 x 1 x 0.25cm (LWH)Connection: VCC/ Trig(T)/ Echo(R)/ GND (VCC: 5V; GND is Ground Wire; TRIG is Trigger Control Signal Input;, ECHO is Echo Signal Output.) HC-SR04 Compatible with Arduino Ultrasonic Sensor Can Send Eight 40 kHz and Detect Signal Back.When Signal Back, a High Level Signal Will be Outputed by IO, and the Duration of the Signal is the Time from Sending Ultrasonic to Returning Module Working Principle:Pull the Trig Pin to High Level for More Than 10us Impulse and the Module Start Ranging.The Module Sends Eight 40KHz Square Wave to Detect Whether a Signal is Returned Automatically.Finished Ranging, If Find an Object in the Front, Echo Pin will be High Level; Different Distance, Different Duration of High Level.So It is Easy to Calculate the Distance; The Distance = (Duration of High LevelSonic: 340m/s) /2.a+Pay Attention:1. Before Powered,HC-SR04 Sensor Module Should be Inserted in the Circuit to Avoid Producing High Level of Misoperate; if Misoperated ,Power the Module Again.2. HC-SR04 Ultrasonic Distance Sensor is NOT Suggested to Connect to Electric Directly, When Connected to Electric, the GND Terminal Should be Connected w/ Sensor Module, Otherwise,it will Affect the Module’s Normal Work.3. When Tested Objects, the Area Range Should More than 0.5 Square Meters and the Plane Requests Smoothly; Otherwise,it will Affect the Results of Measuring.Package Contents:6x HC-SR04 Ultrasonic Distance Sensor3x Mounting Bracket1x 10Pin Dupont Cables 20cm Male to Female1x 10Pin Dupont Cables 20cm Female to Female
Product Features
- Test mode :Using IO trigger for high level signal.( Not less that 10us),The Module sends eight 40 kHz automatically and detect whether there is a pulse signal back
- The detection zone: 0.78~196 in/ (2cm~500cm); High precision: up to 0.12 in/(0.3 cm) Effectual angle: less than 15
- Power supply: 5V DC; Quiescent current: less than 2mA
- Test distance = ((Duration of high level)*(Sonic :340m/s))/2
